This chair is the perfect replacement for the office chair I was using. It is very comfortable and looks really good. Assembly was fairly straight forward. It took two of us just to attach the back to the seat in order to align but otherwise it was fine. I have been able to sit 6 - 8 hours without a backache and that in itself is a plus.
Of course chairs require assembly. This chair came with the best directions and the parts were packaged according to the instruction number. For example instruction 1 had an envelope with all the parts for that instruction etc. I’d have given it five stars but it is too high with the arms down to fit under my desk. But you can put the arms up and it fits.
